<p><P>PROBLEM TO BE SOLVED: To provide an earphone used in common for an antenna whereby an apparatus body being a connection destination of the earphone can be downsized, and to provide a communication apparatus and a mobile phone provided with the earphone. <P>SOLUTION: Since inductive elements (B1, B2, B5 to B8) are provided to a connector (plug CN 1) of the earphone, the apparatus body can be downsized more in comparison with mounting of them to a circuit board of the apparatus body 100. Further, since a room is produced to an internal space of the main body through the elimination of the inductive elements from the main body, the mount design of the main body can be simplified. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
